The Benelli M4 Tactical shotgun has a unique auto-regulating gas-operated (ARGO) system. It features dual stainless steel, self-cleaning pistons located just ahead of the chamber and operate directly against the bolt assembly. It’s a simple and dependable system that eliminates the complex linkage, springs and heavy parts that other semi-automatic shotguns have to depend on. The result: Marine-tough reliability under the harshest environmental conditions. The M4 comes standard with a Picatinny rail for optics, a ghost-ring fully adjustable rear sight and a fixed blade front sight.
